Change and be provided with second gas solenoid valve 25 at the top position of case 23, and one end of the second appendix 27 is connected to UV photodissociation case 28
Air inlet, the gas outlet of UV photodissociation case 28 is connected with exhaust pipe 29, and the top sidewall of purifying box 23 is equipped with pressure-relief valve 26, and
The inner wall of purifying box 23 is provided with thermal insulation layer 231, and thermal insulation layer 231 is a kind of component of asbestos material, the second appendix 27 and goes out
Tracheae 22 is the component of metal material, and the inside of purifying box 23 is uniformly equipped with active carbon stick 30, and the inner wall of purifying box 23
Positioned at the installation having heaters 31 of active carbon stick 30, the both ends of active carbon stick 30 are respectively connected with fixed plate, fixed plate and purifying box
It is bolted between 23 inner wall, and then after exhaust gas to be evacuated to the inside of purifying box 23, by active carbon stick 30 to useless
Harmful substance in gas carries out adsorption treatment, since the surface activity carbon of active carbon stick 30 can reach after long-time adsorbs use
Saturation state causes adsorption effect to reduce or not can be carried out adsorption treatment, in order to avoid repeatedly replacing to active carbon stick 30
It causes to waste, by closing first gas solenoid valve 24 and second gas solenoid valve 25, and heater 31, utilizes active carbon
High temperature regeneration principle, processing is internally heated to purifying box 23, until 30 surface of active carbon stick attachment substance desorption,
It realizes being used for multiple times for active carbon stick 30, reduces waste, by the way that pressure-relief valve 26 is arranged, avoid the air pressure inside mistake of purifying box 23
Height, and the high-temperature gas generated can carry out docking utilization with pressure-relief valve 26 by exterior tubular body, reduce the waste of resource, finally
It is discharged after the inside progress sterilization processing that exhaust gas passes through UV photodissociation case 28 from exhaust pipe 29.
Working principle of the present invention:
Referring to Figure of description 1-6, in use, exhaust gas enters the heat exchanger tube 3 inside water tank 2, heat exchanger tube 3 by air inlet pipe 1
Including the special pipe 301 being placed equidistant with, bend pipe 302 is connected between the end of two adjacent special pipes 301, heat exchanger tube 3
The middle part lateral wall that one end is located at water tank 2 is connected with the first appendix 5, the exhaust gas typical temperature generated in process of production compared with
Height, exhaust gas is behind the inside of heat exchanger tube 3, due to the S-shaped inside that water tank 2 is arranged in of heat exchanger tube 3, and special pipe 301
It is arranged so that the increase of the contact area of tube body and water can effectively inhale the heat of exhaust gas during exhaust gas flowing
It receives, in use process, convenient for as needed, the water inside water tank 2 is used, improves the UTILIZATION OF VESIDUAL HEAT IN effect of exhaust gas
Fruit, and water a part inside water tank 2 can be pumped into the inside of filtrate box 12 by the second water pump 10, in third water pump 16
Under effect, the exhaust gas flowed into inside spraying box 6 by 15 Duis of spray head carries out spray process, and since the water temperature of extraction is higher,
The vapor of generation is also more, and then during spray, enhances the degree of adhesion of harmful substance in exhaust gas and particulate matter, mentions
The high clean-up effect to exhaust gas, after spray, the waste water of generation carries out coarse filtration processing by filter mechanism 18, and filtrate is again
The secondary inside for being back to filtrate box 12 realizes to the multiple circulation of filtrate, and periodically replaces to the water inside filtrate box 12,
Then liquid electromagnetic valve 11 and the second water pump 10 is again turned on to fill the water the inside of filtrate box 12 again；
Further, referring to Figure of description 1-2 and attached drawing 7, after spray, pass through and open exhaust fan 21 and first gas electricity
Magnet valve 24 facilitates the inside that the gas inside spraying box 6 is evacuated to purifying box 23, by active carbon stick 30 to the nocuousness in exhaust gas
Substance carries out adsorption treatment, since the surface activity carbon of active carbon stick 30 can reach saturation state after long-time adsorbs use,
It causes adsorption effect to reduce or not can be carried out adsorption treatment, causes to waste in order to avoid repeatedly carrying out replacement to active carbon stick 30,
By closing first gas solenoid valve 24 and second gas solenoid valve 25, and heater 31, using active carbon high temperature again
Raw principle, is internally heated processing to purifying box 23, until the substance desorption of 30 surface of active carbon stick attachment, realizes activity
Carbon rod 30 is used for multiple times, and reduces waste, by the way that pressure-relief valve 26 is arranged, avoids the air pressure inside of purifying box 23 excessively high, and produce
Raw high-temperature gas can carry out docking utilization with pressure-relief valve 26 by exterior tubular body, reduce the waste of resource, and final exhaust gas is logical
It is discharged after crossing the inside progress sterilization processing of UV photodissociation case 28 from exhaust pipe 29.
